Who said everything has to be super hard? But if you work that out, you'll get 0 for the area. Is that right? It might help to draw a picture. And, hey, area in polar coordinates isn't the integral of r dtheta, is it? Would you look up the right formula for area?

Well, actually, Dick, area in polar coordinates is r dtheta! You didn't say quite what you meant to, did you?
